Application filed September 7, 1926. Serial No. 133,954. l

This invention relates generally to a valve used for diverting` Vwater to either ot two out-lets, and commonlyA Vused in connection with a bath tub and shower.

The primary object ot this invention is to rovide -a valve structure ot simple and economical construction hai/'ing a-single opcrafting member easily assembled, and disassembled to permit replacement off partsD y These objects together with other objects and corresponding accomplishments are obtained by means ot theembodiments of my invention illustrated in the accompanying drawing, in which:

Fig. 1 is a vertical sectional view ot a complete valve, parts thereof being shown in elevation; and'llig. lis arsection .seen on the line 2-2 01"' Fig. 1. 1

Referring with more particularitfy tothe drawing, a. valve casing is indicated by 3.

his casing has a cylindrical wall 'forming a plunger barrel 4, and at one end thereof is an end wall 5 having a valve port 6 therein. The bore of the barrel opens through the casing and is internally threaded as incap 8. In the side wall `ot the barrel isl aport 9 communicating with an outlet chamber provided with an outlet 10 connected to one of thetixtures to be supplied with water. The barrel 1 forms an inlet chamber to which inlets 11 and 12 are connected7 one :tor hotwater and the other for Coldwater. Port 6 communieates` with an outlet chamber having an outlet 18 communicating with the other 'fixture' toy Y Y end with the second outlet chamber, a stem which water is to be supplied. n n K The cap 8 is provided with an internal thread tor engagement by a thread on a stem. Mounted over the tubular extension ot the cap S is a gland nut 111 provided with packing` for suitably packing the stem 15. The stem is provided with an enlarged portion 16 having a thread corresponding to the mounted a valve 17 provided with a washer' to seat over the port 6, and the valve is dimensioned to permit water to passntherearound when it is unseated. Slidably mounted within the barrel andlixed to the stem is a plunger 18 having perforations or holes 19 extending` therethrough to permit water to pass ,trom one side to the other ot the plunger. It will be noted that there is a bevelled edge on the cap 8 adapted to receive a corresponding portion of the at the inner end isplunger 18 and so positioned that when .the valve stein is operated to bring the yplunger 18 against the cap 8, the valve 17 will be otf its seat. At this time the plunger will cover the side wall port 9 and cutoi communica-A tion between the inletchamber and the lower outlet chamber. When the valve 17 is on its seat,'the plunger 18 will lbe in such a posi` tion as to uncover` the port 9.

Assume that the outlet 13 is connected to a shower and the outlet 10 toA a bath tub.' The inlets 11 and 12 may be connected tohot `and Ycold water pipesl tor ,supplying water ofthe desired temperature. Il it is desired to supply water to the shower, valve handle 20 is operated to unseat valve 17 y and posit-ion plunger 18 against the cap thereby covering side port 9. l,Vater may then pass into the inlet chamber, through the port 6, into the` outlet chamber 12 and 'then to the shower. 'llo supply water to the bat-h tub, the .valve handle is operated to seat valve 17, closimg port 6; Port 9 is thereby uncovered by the plunger, and water may pass `trom kthe inlet chamber', through the holes -19 in the plunger, through 'port 9 and to the bath tub.

' What I claim is:

1. A valve structure ot `the' character described comprisinga casing having a firstoutlet chamber and a second outlet chamber separated by an intermediate inlet chamber detined by a wall forming a plunger barrel having'a'` valve port at one endcommunieating with the irst outlet chamber, said inlet chamber communicating at the other extending into said inlet chamber and being provided with a valve for said valve port, a plunger on said stem separating said inlet chamber and the second outlet chamber, there being a passage for placing said inlet chamber in communication with the second outlet chamber controlled by travel of said plunger whereby when said valve is seated to close the iirst outlet chamber, said inlet chamber will be in communication withthe second outlet chamber andwhen said valve is moved to its opposite eXtreme position to open the firstoutlet chamber, said inlet chamber will be closed from the second outlet chamber.

2. A valve'structure of the character doscribed comprising a casing having a first outlet chamber and a second outlet chamber separated by an intermediate inlet chamber defined by a Wall forming a plunger barrel having a valve port at one end communicating With the first outlet chamber and a` passage at the other end communicating with the second outlet chamber, a stem extending into said casing and being provided with a valve for said valve port, a plunger on said stem separating said inlet chamber and the second outlet chamber7 said passage being controlled by travel of said plunger whereby when said valve is seated to close the first outlet chamber said inlet chamber Will be in communication With the second outlet chamber and when said valve is moved to its opposite extreme position to open the first outlet chamber said inlet chamber will be closed from the second outlet chamber 3. A valve structure of the character described comprising a casing having a first outlet chamber and a second outlet chamber separated by an intermediate inlet chamber defined by a Wall forming a plunger barrel having a valve port at one end. communicating With the first outlet chamber and a side port in said Wall at the end opposite to said valve port for communication With the second outlet chamber, a stem extending into said casing and provided With a valve for said valve port, a plunger on said stem separating said inlet chamber and the second outlct chamber and arranged to bridge and close said side port, there being a passage through said plunger for liquid to pass from one side of the plunger to the other for placing said inlet chamber in communication With the second outlet chamber whereby when said valve is seated to close the first outlet chamber said inlet chamber Will be in communication with the second outlet chamber and when said valve is moved to its opposite extreme position to open the first outlet chamber, said inlet chamber will be closed' from the second outlet chamber.

Al. A valve structure of the character de scribed comprising a casing having a first outlet chamber and a second outlet chamber separated by an intermediate inlet chamber defined by a Wall forming a plunger barrel having a valve port at one end communicating With a first outlet chamber and a side port in the Wall atthe end opposite said Valve portfor communication With the second outlet chamber, a stein extending into said casing and provided With a valve for said valve port, a plunger on said stem aroutlet chamber and a second outlet chamber separated by an intermediate inlet chamber defined by a cylindrical .Wall forming a plunger barrel having a1 valve port at one end communicating With the first outlet chamber and aside portin said Wall at the end thereof opposite to said valve port providing for communication bet-Ween said inlet chamber and said second outlet chamber, a stem extending into said casing andprovided With a valve for said valve port, a

plunger on said stem arranged to bridge and close said valve port, there being a seat for said plunger in said casing for said plunger to rest therea'gainst When the latter bridges said side port, there being a passage through said piston for a liquid to pass from one side to another whereby When said valve is seated to close the first outlet chamber said inlet cha'mber Will be in communication with the second outlet chamber and When said valve is moved to its opposite estreme position to open the first outlet chamber said inlet chamber Will be closed from said seeond outlet chamber. Y

In Wit-ness that I claim the foregoing I have hereunto subscribed my'name this 13th day of August, 1926.
